Resolution

Ensure your end users' languages are appropriately set on their profiles. Adding multiple languages to Support advises how to bulk update your end users' languages if they are incorrect.

Create default dynamic content for each of your commonly used text (generally written in your account's default language)

Add variants for each language you support.

Replace the original text with the dynamic content placeholder in all macros, triggers, and automations where the original text appears.

When these triggers, automations, or macros containing dynamic content placeholders are used, Support will detect the user's language (or follow what is set in the user's profile) and send the reply in the correct language.
